The Wonder Island Boys

Do you remember Harry after discovering the treasure and the skeletons of the pirates in the cave near the Cataract that we heard the doleful sound of some bird while going down the hill? Yes; that cry was something like it. Do you recall the name of the bird George? It was the Alma Perdita. I remember now; it means the 'Cry of the Lost Soul.' Yes; but I don't think that came from a bird. It is more like an animal of some kind. Don't you hear a sound that seems to be answering it? It does seem so; I think John would know what animal it is; but it is too late to speak to him about it to-night George.
